Consiste en crear paquetes o peticiones especialmente malformadas para ir m\u00e1s  all\u00e1 de las especificaciones del protocolo. <\/p>\n<p>El objetivo es comprobar como manejan  los dispositivos, las aplicaciones o el propio sistema operativo que implementa el  protocolo, estas situaciones an\u00f3malas que desgraciadamente no se han tenido en  cuenta en la implementaci\u00f3n y casi siempre terminan en un error, denegaci\u00f3n de  servicio o en alguna vulnerabilidad m\u00e1s grave.  Gracias a la t\u00e9cnica de fuzzing se han llegado a encontrar gran cantidad de ataques  de DoS y buffer overflows en los productos que imp ementan los protocolos SIP y  H.323.<\/p>\n<p><strong>Igenier\u00eda social <\/strong><\/p>\n<p><strong>SPIT: Spam over Internet Telephony<\/strong><\/p>\n<p>El SPAM es uno de los problemas m\u00e1s graves en las comunicaciones hoy en d\u00eda, y  la telefon\u00eda IP tampoco se escapa. Recibe el nombre de SPIT (Spam over  InternetTelephony).<br \/>\nSe prev\u00e9 que esta tendencia de realizar llamadas y  llenar los voicemail de los  usuarios con mensajes pregrabados crecer\u00e1 durante los pr\u00f3ximos a\u00f1os a medida  que se generalice el uso de telefon\u00eda por IP.   <\/p>\n<p><strong>Vishing: Voip Phishing <\/strong><\/p>\n<p>Al igual que ocurr\u00eda con el SPAM las amenazas de phishing suponen un gran  problema para el correo electr\u00f3nico. Las denuncias  por robo de informaci\u00f3n  confidencial de forma fraudulenta est\u00e1n a la orden  del d\u00eda y exactamente las  mismas t\u00e9cnicas son aplicables a la plataforma VoIP. <\/p>\n<p>Gracias a la telefon\u00eda IP un  intruso puede realizar llamadas desde cualquier lugar del mundo al tel\u00e9fono IP un  empleado de la empresa y con t\u00e9cnicas de ingenier\u00eda social y mostrando la  identidad falsa o suplantando otra conocida por la  v\u00edctima, obtener informaci\u00f3n  confidencial, datos personales, n\u00fameros de cuenta o cualquier otro tipo de  informaci\u00f3n. Las opciones son pr\u00e1cticamente ilimitadas y al igual que el SPIT es  posible que el n\u00famero de incidentes de este tipo se disparen en los pr\u00f3ximos a\u00f1os.   <\/p>\n<p>Tomado de:<br \/>\nArroba, M, &#038; Salazar, M.
